To me? I didn't receive anything I guess the information that's missing (or it could be there I'm not sure as the thread has become longwinded), is what happens with the shield. Is it timed? Is it like a life for the player and stops them losing? Your problem probably lies with the fact that you have a shield spawn, your stars can keep increasing and you still have a shield equipped. I'm not sure what the point of the shield is though so if you could explain that. Does it equip automatically? I see that you add a shield point on every few starpoints but it's not clear what you want the shield to do in relation to the game.

Eventually, when the shield is equipped it will attract nearby stars to the ball. Acting as a sort of vacuum, and allowing the player to score more stars. Also, allowing the player to purchase more shields from the store when they have run out.
